For this problem, we're going to start with x minus y plus 3 equals 0.
00:07
And the second equation it gives us, i've kind of read it backwards, so i'm going to write it the way we're a little bit more familiar.
00:14
So it's just going to be y equals x squared minus 4x plus 7.
00:23
So as far as solving these graphically, we can use most online software.
00:31
We can just plug these in just as we see them and find where the lines intersect.
00:36
However, on a test and in a pre -calculus course, you're probably going to have to use a ti or a graphing calculator.
00:44
And most graphing calculators require you to have things in the form y equals.
00:48
So our second equation is already done.
00:50
So that's nice.
00:52
Our first equation, we just need to write it as y equals...
